I hope this post is ok from administrative pov, I've searched the forum and couldnt find a similar bug report.

Death summaries (how many times DIRE killed RADIANT) are missmatched between player 2 and player 3.

Repro Steps:
Party w/ human, create lobby. Your party joins 3rd slot (purple) and fill all the remaining slots with bots.

At the end, scoreboard show 3rd player, purple, before 2nd, teal w/ the right KILLS stats.
When checking the DIRE rows, to see who killed purple, you see purple hero icon with teal hero stats:

Expected Result:
Correct K/D stats and icons in scoreboard.
